Nucleophilic carbenes in asymmetric organocatalysis

Article Abstract:

Many chemists have tried to perform enzyme mimetic asymmetric carbene catalysis using the coenzyme thiamine. These experiments have resulted in successful enantioselective benzoin condensations and enantioselective intramolecular Stetter reactions.

Enamine-based organocatalysis with proline and diamines: the development of direct catalytic asymmetric aldol, Mannich, Michael, and Diels-Alder reactions

Article Abstract:

Enamines and imines are very important in enzyme catalysis, particularly with aldolases. The conversion of enzymatic enamines and imines into a versatile catalytic asymmteric strategy powered by small organic molecules is explained.
